If you are handy, try it out! I've built quarter wave transmission line speakers tuned to say 40Hz or 45Hz using four and five inch drivers and had some pretty deep bass from them. The output rolling off below the system resonance, but still heard below that. The drive units my have 40, 50 or even 60 Hz resonance, but the acoustic line resonance is excited by them to below that and the bass is extended further.
Reflex designs often use a similar trick, with port output extending below the driver resonance and reinforcing the low bass.
It is impossible for anything digital to sound analogue, because it isn't analogue!
